"Vi Cell is easy to use. However, I wish it had more comment capability (a way to enter information about each sample). Photos are very large creating a data storage problem, but overall I would recommend the product."

"The image analysis parameters had to be modified to give comparible values as measured by Cedex and manual hemcytometer methods for the cell types used in our labs. The system is more trouble free than the Cedex."

This data is essential to the decision making process for basic tissue culture cell passage and maintaining optimum culture conditions in bioreactors. Cell and tissue culture applications in life science research, including recombinant protein and biopharmaceutical production, require the accuracy, precision and automation available only in the Vi-CELL cell viability analyzer.

Determining cell concentration and viability accurately and precisely is a requirement in research and in the production of biopharmaceuticals. The Vi-CELL XR automates this process that eliminates variability inherent in manual sample preparation and counting.

The Vi-CELL automates the widely accepted trypan blue cell exclusion method. Historically, cell viability determinations were performed manually using a light microscope and hemacytometer. This technique has major shortcomings due to subjective determination of cell count, as well as manual, time consuming steps. In comparison to the manual technique, the Vi-CELL automatically performs the trypan blue with video imaging of the flow-through cell. Results are obtained in minutes.
